From version 6.3.1, IOS XR supports "if community length" in route-policy.

On the point of as-path length limit, Yes I know of at least one tier-1 that does it and since I left some 8 years back 
I do it everywhere I go.
In addition to the above (best common practice, id' say)
-on junos you can do community length limiting
-and on cisco you can do attribute filtering  -hence my question to this forum some time back about whether folks do 
filter all the "experiments" for the sake of running a successful business (paraphrasing...)
