You mean, a Tails issue that happens to affect obfs4 since it likes to
write large-ish packets, and what may be a Linux kernel issue that
possibly makes the PLPMTUD code not that great.
I have a packet capture that I need to go over but, since it is tcpdump
output from a terminal and not a pcap file I've been putting it off,
but the fact that TCP/IP breaks when write calls are done when the
system is breaking PMTUD is not an obfs4 issue.
In sane environments where PMTUD works, obfs4 has no issues with
shorter than normal MSS.
