The 'LM Roman 12' you're referring to in your fc-list output is just an
alternative family name for this particular file and is not technically
related to the design size property of that font, and I think using it
in a pattern should only treat it as that and not try to guess some
other property values out of it (or substitute it with the Preferred
Name, for that matter).
NB. it's the second value in the 'family' property, hence most pickers
won't show it anyway.

Users will always be able to switch the property off (once it's
implemented) by means of fontconfig rules.
