Some contributor (i.e. me) was not happy with this nudging though. The
other day I switched to some branch (probably 'pu') and the build
failed because, guess what, I didn't have pcre2 installed. If I set
USE_LIBPCRE1 then I lose pcre support when switching to other
branches. And no, I don't want to install libpcre2, not when I'm
forced to this way.

188 packages on Gentoo optionally depend on libpcre, 6 packages on
libpcre2. Chances that a Gentoo user has libpcre2 already are rather
low. I'll revisit my installation when the level of libpcre2 support
grows a bit more than that. You can nudge distributors directly,
probably more efficient too.

Agreed.
