Maybe improvements in Org could make your bug less prominent...

Then again, it could be that there's some trick up Org developers'
sleeve that they could teach you.

In general, anything surprising/inconvenient/buggy should be reported,
you can never know what will come out of that.

Submitting changes in C is a bonus, it's good enough to describe the
use case and ask for primitives to support it.  Someone else might get
motivated.  It could even be very easy, like with fci-mode.

I'm quite sure that some of the bad reputation of Emacs is due to
incredible things people do in Lisp, which then make Emacs look
sluggish and bloated.
