Define 'normal'.  Just because userspace software depends on something 
doesn't mean we should force that on everyone, even if disabling it 
could make some systems fail to boot (that is an inherent risk in 
building your own kernel).  dnotify (inotify's predecessor) is an 
excellent example of this: nfs-utils depends on it, and that not working 
can definitely make a system fail to boot, yet it is not hidden behind 
some other config option, but defaults to being on.

Making inotify default to on (like dnotify) is a better solution to 
this, anyone who is going around turning off options that default to on 
in kconfig should be prepared to deal with a system that doesn't boot 
anyway, and EMBEDDED is intended (AFAICT) for saving space on systems 
with limited memory, not hiding userspace dependencies that have other 
legitimate reasons to be disabled.
