I think Lars is saying both, though the other reasons are more important.
Lars makes a good point that common idioms like
(file-attribute-modification-time (file-attributes F)) generate
unnecessary garbage. And it's more than just GC overhead: at a lower
level, 'statx' on GNU/Linux can be significantly more efficient than
plain 'stat' when retrieving just a subset of stat info (such as, just
the file timestamp).
Getting various flavors of the current time is another issue. This
related to the polishing that Stefan referred to with the new CPU time
primitive.
I'll try to shake some time free to think about this more.
