And it tells us The Truth (TM).
Under macOS, PIPE_BUF is very short:
--8<---------------cut here---------------start------------->8---
23:33:50.197963 tramp-send-command (6) # getconf PIPE_BUF / 2>/dev/null || echo 4096 2>/dev/null; echo tramp_exit_status $?
23:33:50.200794 tramp-wait-for-regexp (6) #

tramp_exit_status 0
///ec22873252400ed5da2786d09e65ca05#$
--8<---------------cut here---------------end--------------->8---
Tramp tries to set a very long PATH variable (this is the essence of the
test), creating a temp file via a heredoc command. With other OSes, this
trick works. But it refuses to work for you:
--8<---------------cut here---------------start------------->8---
23:34:00.273274 tramp-send-command (6) # cat >/tmp/tramp.21cf9w <<'ee34a56d9cb9cbd177c29dcaca509be9'

As you see, Tramp is stalled for 19 seconds, and then the timeout kills
it. I will see whether I could rearrange the command sequence. Maybe
writing the temp file just in shorter chunks, or so.
Best regards, Michael.
