You haven't noticed that PHP 7.3 moved to PCRE2, huh?

Or are you talking about updating during a series? The bundled library is updated when it's safe to do ABI breaks: when new series are released. If any individual fixes are needed afterwards (eg, security patches) then they're cherry-picked.

i have, but how does that change anything for 7.2?

to be honest the fact that 7.3 is using pcre2 and the amount of bugfixes in distributions is what makes me worry when bundled stuff get that less updates

If you're concerned that the bundled version isn't always totally up to date then use your own version that is.
