Internal voice says to me that there will be no answer from Perl
developers :)
No answer (at all or next waited answer in thread) is a frequent thing in
a perl bug tracker.
It's obvious that COMMIT realization have bugs in Perl
(https://rt.perl.org/Public/Search/Simple.html?q=*commit). Users worries
about this but Perl developers no.

PCRE have much more consistent and documented behaviour of backtracking
control verbs.
So it seems be best to not change PCRE behaviour around COMMIT and THEN in
unnecessary attempts to achieve full compatibility with Perl.

You be free to close this thread.
