Embedded can also much be more tolerant of ABI changes - if you change
the internal time_t representation in your embedded firmware then the
only people who care is your software engineers.  Do the same on a
desktop platform and every library and application has to be recompiled,
lurking assumptions about representations are suddenly surface, and any
library or plugin ABI involving time_t has a compatibility break that
needs to be managed somehow.

It can be done (Linux had multiple complete ABI changes in the 1990s,
plus a more subtle approach to file offsets) but it’s disruptive and
painful.
