# This job runs a stripped down version of CI to test the MSRV. The specific
132+
# reason for doing this is that the regex crate's dev-dependencies tend to
133+
# evolve more quickly. There isn't as tight of a control on them because,
134+
# well, they're only used in tests and their MSRV doesn't matter as much.
135+
#
136+
# It is a bit unfortunate that our MSRV test is basically just "build it"
137+
# and pass if that works. But usually MSRV is broken by compilation problems
138+
# and not runtime behavior. So this is in practice good enough.
