As a frequent user of `grep -P`, I'd like to know whether there is any
loss of functionality with the switch.
As far as I know there is no intended loss of funcionality. PCRE
test suite was enacted by the PCRE2 project. The same applies to the
code. PCRE2 code was refactored. Not written from scratch. Regressions
are fixed on the on-going basis. You can read PCRE2 NEWS file (or more
verbose ChangeLog file) if you are interested in the fixes.
