If I remember things correctly, I think using ":application eshell" was 
a suggestion from Michael Albinus. (I don't think I'd have come up with 
the idea on my own, since I didn't know much about connection-local 
variables at the time.)

However, I think can be a good move to use a unique application name 
when it makes sense because it reduces the chance of conflicts. For 
example, in a future version of Eshell, I might make 
'process-environment' connection-local for ":application eshell" (it's a 
long story). This would let users change remote env vars in Eshell 
freely without interfering with the ":application tramp" remote env 
vars, which would get used in other cases (e.g. when opening a remote 
file or using M-x shell remotely).
