Mostly convenience (one less level of indirection).

For identifying sub-changes between PORTVERSION/PORTREVISION bumps.

For keeping track of heritage when using a local mirror of
FreeBSD ports, but slightly divergent, for local products.  Mainstream
FreeBSD users don't care about this one, but people who use FreeBSD
and add value might.  For instance, PC-BSD might fall into this
category (not trying to put words in their mouth - just guessing).
$work users might.  Just one specific use case here - we have to
maintain some older 4.x based products and have to have our own branch
of the ports tree.

For aberrant maintenance issues where I have had local screwups.
These, of course, are _extremely_ rare personally ;)  Anyway this
is quite a weak entry on the use case list.

Just like for ident strings in binaries where you can generally get
close enough by knowing uname, you can (as you mention) generally get
close enough to the plist source version from

Removal doesn't bother me that much, but I found it useful on occasion
over the years.
