The plan line has to be mandatory for this feature to work as
intended (i.e., for the TAP consumer to determine whether a
producer has run to completion or not).  An optional plan would
be useless.

Other TAP consumers behave similarly to Automake's in this regard.
Take prove for example, the de-facto reference implementation of a
TAP consumer, which outputs a similar error message:

  % prove -ve sh test.sh
  test.sh .. 
  ok 1
  All 1 subtests passed 

  Test Summary Report
  -------------------
  test.sh (Wstat: 0 Tests: 1 Failed: 0)
    Parse errors: No plan found in TAP output
  Files=1, Tests=1,  0 wallclock secs ( 0.03 usr +  0.00 sys =  0.03 CPU)
  Result: FAIL

The bug is in the TAP documentation.
