Sorry; this is my bad.  I'll close the bug.

I had both Emacs 26.3 and 27.1 open.  I didn't realize
I was trying that in 26.3.  This is the error, FWIW:

Debugger entered--Lisp error: (error "Unknown rx form 'literal'")
  signal(error ("Unknown rx form 'literal'"))
  error("Unknown rx form `%s'" literal)
  rx-form((literal "abc"))
  rx-to-string((literal "abc") t)
  #f(compiled-function (&rest regexps) #<bytecode 0x31a9f25>)((literal "abc"))
  (rx (literal "abc"))
...

There was no doc for `rx' in the 26.3 manuals, but I
somehow mistakenly used a 26.3 window for that test.
