Only a few important points you forgot to mention.
1) Mid-boom sheeting requires larger main sheet gear as you have less

leverage compared to end-boom sheeting.

Yeah, so? You add more main sheet gear.

2) The forces on the main sheet are generally higher and the boom is
far more susceptible to breakage, as the outer end of the boom is
essentially unsupported and the mid-sheet mounting weakens the boom
where it is attached.

I can't find a single instance of a boom breaking (outside of really
old boats like Neal's) from this arrangement. Like a deck stepped mast,
cable based steering system or RF sails, it can all work well when
designed properly.

3) Prevents the use of boom roller furling gear for the mainsail.

I've seen mid boom sheeting on in boom reefing mains. That said, after
sailing three boats over the last two seasons with in boom and in mast
reefing, I wouldn't want it.
