This.

If you were able to handle options that didn't limit goats, then you
can add an alternative profile that doesn't include any max-goats
constraints:

a=rid:1 recv max-goats=47;max-fr=50
a=rid:2 recv max-goats=22;max-fr=20
a=rid:3 send max-goats=44;max-fr=20
a=rid:4 send max-goats=22;max-fr=10
a=rid:5 recv max-fr=10
a=rid:6 recv max-fr=5
a=rid:7 send max-fr=10
a=rid:8 send max-fr=5
a=simulcast: send rid=3;4,7;8 recv rid=1;2,5;6

(I've probably gotten the syntax off here, but I hope that this is clear enough.
