If a fix is possible, and someone backports it, a release should be 
made. If person B does not have access, there's nothing stopping them 
cutting their own egg and putting it up on their own egg server. I know 
I've had to do this before for packages like xlrd, which often have 
development but are extremely rarely released, and have maintainers who 
don't care about eggs at all.

Indeed, they only need to create releases for things they care about, 
it's the open source way :-)

I'd love to see some actualy evidence of that ;-)

Oh?

I'm -1 on this compromise. If a package needs a bugfix of another 
package to work, then it should specify it.

However, I *am* -1 on specifying a later version of a package just 
because it's available ;-)
