Yup, eventually, but I don't normally worry about it until we are
approaching a release date. tzdata changes often come in bunches
around the spring and fall equinoxes, which is when governments
tend to rush out DST changes without thinking about lead times :-(.
So it's entirely possible that 2025b will already be obsolete by May.
(See for example ecbac3e6e and d8fc45bd0, when I thought I'd waited
long enough and was wrong.)
The situation might be different with a tzdata release that affects
our regression test results, but I don't believe this one does.
