FTR, I try to always assume that no question is stupid. Only answers can be.
My understanding is that there's no universal answer to this; for a lot of
packages, the answer is "nothing"; it will just work. For some packages
though, if they embed executable paths such as /usr/bin/grep where only
/bin/grep exists on the host system, this will break.

A merged-/usr has a /bin → /usr/bin symlink; so a .deb package unpacking
/bin/grep will make that binary end up in /usr/bin/grep; but the
/bin → /usr/bin symlink ensures that you can either access /usr/bin/grep
directly or /bin/grep through the symlink.
An open question I think is whether dpkg should/could at one point in the
future always unpack binaries to /usr/bin and never in /bin no matter what the
package contains (+ setup a convenience symlink in /bin if /bin is a real dir
?).
