Should not an increment of zero be flagged as an error, and not ignored?

Thanks for the report.
However, I don't think this is a bug but more a misunderstanding
on your side how seq works.  It's clearly documented that the
second number (if 3 are given) is the increment.  As you passed
0 as value, the target 10 is never reached, and therefore seq
continues to produce output.  Thus, it exactly does what you
told it to do.  What else would you expect?

Have a nice day,
