Oopps... you're correct.  Unfortunately I have no control on the UMN
website so hopefully someone from UMN will read this and fix it.

STYLES (SLD) are not supported in server mode you are correct.  This in
one of the features that clients ask for often so hopefully we can get
this funded and add it to the software in the not too distant future.

In client mode (when you embed WMS layers in a MapServer mapping
application), you can already use styles without MapServer being aware
of them.  We've done it in a few apps... just requires an understanding
of the way SLD works in order to define your SLD document, that's the
tricky part.

It is fully supporting all "required" features, yes.  So from this point
of view it is fully compliant with the spec IMHO.

As you wrote it doesn't support all options of the WMS spec... but these
are added as needed (and funded ;)

Agreed.  WMS is an importnat feature and should be listed on the main
page.  But if all features of MapServer were listed on the main homepage
then it would become a several pages document!   :)

GetFeatureInfo is optional and is supported.  I don't have other options
in mind... I think SLD is the main one missing.
