Yes, essentially just the fact that compilation takes longer.

When we compile Emacs the makefile uses
`batch-byte-native-compile-for-bootstrap' to produce both the .elc and
the .eln.  As the eln is produced as side product of the .elc to have
the makefile dependecy model work we can't rename the .elc before the
.eln is also finished even if we could, otherwise in case of
interruption we may have the .elc produced but not the .eln.
