You presumably did "tla add-library expensive-foo" for revision
"expensive-foo", then.  Tag it as permanent somehow (I'm not familiar
with library structure, so don't have an implementation), and require
a --force option to "tla library-remove" for "permanent" revisions.
Alternatively, create an internal "library-cache" command, and make

"library-add"    = "library-cache --permanent --add" (for cmd args)
"library-add"    = "library-cache --add" (for non-cmd args)
"library-remove" = "library-cache --force --delete"
