Let's make sure everyone is in synch about what is being proposed:

     The suggestion is to drop a tag from the *DNS record*, /not/

What is the benefit of having the DNS record list possible algorithms?

It's not a matter of possible algorithms, but which algorithm is to be 
used to interpret p=.  This having been said, I think your major point 
is that you do not see a benefit in stating the algorithm in the key 
record when it has already been stated in the header, that perhaps there 
is some nebulous potential downgrade attack.  Is that right?
