Well, in the man page there was incorrectly extra space between -d and
the optional argument. Fixed yesterday.

What? The argument for -d is optional, it's reason why we care about
'='. I think it's obvious from the code.
swapon -p -2 -d /dev/sdb1
is pretty valid.
Note that -d,--discard has been implemented in 2010, and extended by
'once' and 'pages' later in 2013.
