At some point we must realize that we are shooting for fun. We just like to make our guns go "Bang". Some guys can't stand some can't sit how are you going to have any kind of meaningful competition? I suggest you forget standing and take out some ironing boards and folding chairs. I think that's how "table shooting" got started.

I see this issue from both sides. When younger I was an up and coming offhand shooter, placed 3rd in the SE regionals the only time I entered. But my job got in the way and I drifted away from match shooting. Point is, I was young, with good eyes, and really liked standing on my 2 feet and shooting offhand.
But now things have changed, I still have the desire but I don't have the means. A total knee and hip replacement on the left side, and now bone on bone knee along with hip pain on the right side has probably hurt my offhand more than anything. Just can't stand steady anymore. Add to that a deteriorating joint disease in both shoulders makes it pointless to even enter a match. My eyesight also went south and now I shoot with a peep sight.
What I would like to see is a class for us wore out oldtimers, but leave it open to any age with the right physical limitations. In it would be at least two targets, one is an offhand but you can use any kind of shooting aid such as a monopod, tripod or stick to help manage the weight of the gun over a period of shots. The other would be some kind of table shoot sitting in a chair. Most of us have a problem with sitting on the ground and then getting up again, so a chair is doable. And make any kind of open sight to include peep sights legal as most of us also have progressing vision problems. Just no scopes, red dots etc. Please.
I think as a whole our true muzzleloader ranks now consist of mainly older shooters. Many no longer compete because they are forced to abide by a young man's rules which no longer work for them. So it's maybe time to offer these guys some shooting that more meets their ability.
And it's a fact that almost everybody will be like us in some way eventually. And nobody wants to be turned out to pasture.
