I asked this same exact question several years ago.  There are many replies
with different takes.  I would skim through Alex's posts, there is really
nothing worth reading except it will break the SIP RFC handed down by the
internets themselves.

I use nat=yes all the time and it works just fine.

Nobody actually answered the question about the bad side, they just argued
about the SIP RFC.

Many others agreed to make it default behavior and that setting nat=yes
gives a an extra degree of security.

RFCs are great and all, but in the real world, phones just need to work.

Thanks,
