I agree as well. Related code changed in 9.4:
- 
https://orgmode.org/list/CALOSHoRNnLxJMa6jnrt-iKiE-b9f9o3CLQDxFekrZVYiyzE0Qw@mail.gmail.com/T/#u
- https://code.orgmode.org/bzg/org-mode/commit/be93859c78

The following is just my opinion, not a request for an update of the patch.

Maybe it will be better to change `org-babel-tangle-collect-blocks' 
function in lisp/ob-tangle.el instead and to wrap passed argument in the 
suggested way (at first I thought of non-capturing group "\\(?:" "\\)", 
but it is not necessary since the regexp is passed to `string-match-p'). 
I suppose, it is more reliable default. If anyone really needs partial 
match, he may express it explicitly by adding ".*", "?", etc. I hope, 
such change will break no existing code.
