Then you should argue for this; see the arguments against it here:

Correct.

Actually, you can do either of this:

1)
  # remove `silent-rules' from AM_INIT_AUTOMAKE and add
  : ${enable_silent_rules=yes}
  AM_SILENT_RULES

2)
  # remove `silent-rules' from AM_INIT_AUTOMAKE and add
  AM_SILENT_RULES([yes])

but the latter is still undocumented, as result of the discussion
referenced above.

Cheers,
