I don't think that's really a fair characterization -- almost all of
the autoconf sed portability caveats concern weird corner cases in the
dusty corners of the language (and some are "common" issues with other
tools, i.e., avoiding ^ and $ inside of regexp groups).

For typical straightforward usage, there seems little problem.

[The main portability problems I've actually _noticed_ with sed are
the "-e" versus ";" issue and what happens with "\n" in various
contexts...]
