Yes, but for the kernel.  You want to reduce the time to /sbin/init
being run by removing anything you don't want or need, and you want to
have the udev coldplug run as fast as possible.   And if you can do away
with slowpoke stuff like initrd and driver firmware loading in the
critical path, do so.

Remember that module loading is serialized, and also that way too much
stuff will try to autoload nowadays (the rule in kernel-land is to
provide autoload information to EVERY module you can).

So you might want to look at the udev coldplug pass...
