I have Portage 2.1.1 and it has no such line. So this looks like a newly

I'm not sure whether this is a bug, because I'm not sure why it touches
the destination in this case. Probably, rather than playing with the
mtime, they should just record the fact that the file is needed by another
package and should not be unmerged in some database somewhere.

Very very likely. Fast processors and caching mean that 99% of the time
you will not get a clock tick during these operations.
