There’s a whole section on the page with the header “Concern over numerous patches to the match ergonomics feature”.

So if your question is literally, “Does anybody else...” then the answer is yes:

“Users have expressed concern with the frequency of patch releases to fix bugs in the match ergonomics verification by the current borrow checker on a variety of Rust’s forums. ”

If the question is more about being concerned yourself, do the reasons listed in the link address your concerns?

There have been 3 patch releases that include borrow checker fixes related to the match ergonomics work in the last 45 days.

The latest of these actually address your concern directly.

No? I don't understand why it's concerning at all. Progress is being made. Who cares?
