I can see that argument for IOS and IOS XE, but for something that is 
supposed to be fully modular like IOS XR, having another control plane
feature in a separate process (which you do not run when you do not 
want it = no impact) should be save enough.

Note the emphasis on "control plane" - no tricky hardware programming
interaction, just central CPU handling specific protocol packets.

I can also see the wish to avoid spending development resources on a
"new protocol that nobody uses", but since the feature is already there
on XR on CRS-1 and ASR9k, if that is a serious argument, it opens up
lots of question marks on internal development processes...

(OTOH, EIGRP seems to be there, as an optional bundle, as has been
answered already - so it's just the documentation of "supported features"
on the platform web site which is/was misleading)

I can see that.

Now that's good news :-)  (though "the platform" could be NCS-5001
or NCS-5501 here, which are different enough that it's not clear if
this holds for both platforms...)
