I sent a message on the bug report, but think that it is worth mentioning here too. There is a discussion on the glibc mailing list about what syntax should be standardized taking into account existing implementations [1]. I think that discussion should be resolved before changing anything.

[1] [[PATCH] regex: Add \A and \z synonyms to \` and \'](https://inbox.sourceware.org/libc-alpha/d357ebe7-9aef-41f7-98da-5fa891f8064a@cs.ucla.edu/T/#m6dcdfc0466b896647fce7be5569d8d39af797125)
