I did not know about the new directory practice, thanks.
From what their site says it looks like it was done this way to keep ARM native stuff separate from old intel code which can still work under Rosetta. But I don't see any indication homebrew stopped linking system libraries as a matter of course (correct me if I'm wrong).
MacPorts makes a point of not doing this. /opt/local is its own universe and dependencies can be upgraded more or less aggressively than Apple's. https://trac.macports.org/wiki/FAQ#syslibs
I much rather them use system libraries than build parallel libs that don’t go through Apple’s vetting / changes. This has worked well for me in practice. I’ve actually never run into an issue where the system library got updated and that broke homebrew’s apps.
That seems like a totally valid perspective. Macports page I linked claims that Apple is often too slow to update, and in some cases only does so when there is a security breach. I can’t vouch for if that’s true. In my experiments maybe 10 yrs ago it took substantially longer for me to install a certain set of packages on Macports vs homebrew due to the parallel library thing. But I had had some broken packages with brew and found Macports more reliable.
Does seem like something Apple should fund / handle IMO.
