No it isn't. It puts more strain on the rig and gives less
leverage to the trimmer.

Leverage problem is easily solved with more purchase.

Except that then you need more blocks & longer line

... Swan seems to
think it works! So did C&C, Sweden...

Like I said... it was a common arrangement back in the days
of boats that were driven primarily by genoa and had small
main sails with short booms.

... would like to see a list of pricey
boats you wish you could own with mid-boom sheeting?

How about a Shannon 43?
How about a Swan 48?
How about a nice new C&C 121?

Actually, the Swan and the C&C 121 have mid-boom sheeting as
an option, and it's not one that would be chosen by a
serious sailor for the reasons I've already given.

I don't know about the Shannon 43 but it's not a performance
boat by any stretch of the imagination.

.... Perhaps you'll own one
someday and follow in my footsteps!

I don't think so. Sailing is a lot more fun. try it some time.
