I have noticed in many of the pictures of panels and interiors that the depth of the instrument panel and height of the stick is clearly going to limit full nose down
elevator. Perhaps folks think they will never need full nose down elevator. While we are not supposed to spin the airplane intentionally I am concerned that recovery from an inadvertent spin might be slowed or impossible with limited forward stick travel. I wonder how folks with panel extensions and full length sticks are meeting the design elevator travel limits.
On my airplane the panel is about 1/2 inch deeper than stock. By shortening the vertical straight portion of the stick to as short as possible and still mount an unmodified grip, I have the clearance necessary to get full down elevator. The stick ends up about two inches forward of the lower edge of the panel at the full nose down position.

I added a short extension to the curved portion of the stick, creating additional bend. Both sticks clear the panel.
I used pictures on Scott Schmidt’s site. There should be messages in the archive.
Do not archive

I haven't got to the point of having my panel installed and a stick grip to test, so this is a 'off the cuff' remark.
I fly a Pitts .... well, let's say I hang on tight .... so that's where my comments comes from.
If there is interference with the panel, it's not going to make a whole lot of difference in elevator throw. Bending the curve a little more will help or eliminate the problem.
To address your spin scenario, proper spin recovery is to briskly apply rudder opposite the spin to stop rotation and then apply forward stick (with neutral rudder at this point) to get airflow over the control surfaces. How much forward stick depends on the size of the elevators, and the elevators on the -10 appear to be more than sufficient.
Most non-aerobatic pilots would have to really fight to push that stick full forward ..... it's a real unnatural act. As soon as the butt gets light in the seat, they change their mind.
I have yet to hear of the spin characteristics of the -10 so don't have any data. From what I see, looking at the -10, is that it should be very controllable entering and exiting a spin. I'm sure it's been spun, but nobody wants to be flamed for it. I also think inadvertent spins are due to poor piloting skills.
Another way to look at the situation .... how many times do you pull full stick?? Ever?? In any non aerobatic airplane??? Well, go yank on the up elevator and feel the Gs ..... and picture that same feeling up against the seatbelt pushing.
I guess I'm trying to say I don't think it's really a problem.

Dick if you look at vans required throw
For the rv-10 it is 20-25 degree.
I think that with proper adjustment and sticks
At reasonable lenghts there should be no
Problems at all. Some people might have a problem
If they make there sticks to long. Even
With the standard panel there could be a problem.
I have been in a 10 with a stock panel and
The stick goes under the panel at full deflection.
It missed the bottom of the panel by 1/4".
That would worry me more than hitting the
Panel.
Just FWIW

My SteinAir panel is a bit lower than the stock panel and I have Infinity grips. I had to put just a slight bit more bend in the sticks to insure clearance.

There's a bit of manufacturing tolerance in the sticks and/or attach hardware. I had to bend one stick a bit, while the other was okay! (stock panel).
