Why dependency re2 is disabled?

Description:

libvpx has been disabled due to a bug in Qt, while re2 have been disabled without any clear reason. It's important to note that re2 is still essential; however, it is statically linked to the version bundled with Chromium. Is this the best approach?

My actual issue

I am maintaining the qt6-webengine package for the unofficial Arch Linux loong64 port, which has been stalled for a while due to a linking problem. The error message is as follows:

/build/qt6-webengine/src/build/src/core/RelWithDebInfo/loongarch64/obj/extensions/common/common/common_jumbo_14.o: in function `bool re2::RE2::Arg::DoParse4ary<unsigned long>(char const*, unsigned long, void*)':

I'm wondering if we should consider using the system version of re2 instead of relying on the one provided by Chromium. What are your thoughts on this?
