reb moshe’s isur to make eruvin is based on opinions not brought down in shulchan aruch- that was his deredch hapsak, so just like he can argue with shulchan aruch and nosai keilim, so too other rabbonim can argue with reb moshe and just follow there way of psak based on the sh”u.
according to r”t, only his tefillin are kosher, only is zman is the halacha, etc
