Potentially naive question - the trace point holds enum skb_drop_reason.
The user space can get the names from BTF. Can we not teach user space
to generically look up names of enums in BTF?    

That puts a hard requirement to include BTF in builds where it was not
needed before. I really do not want to build with BTF just to get access to
these symbols. And since this is used by the embedded world, and BTF is
extremely bloated, the short answer is "No".  

Dunno. BTF is there most of the time. It could make the life of
majority of the users far more pleasant.

BTF isn't there for a lot of developers working in embedded who use this
code. Most my users that I deal with have minimal environments, so BTF is a
showstopper.

I hope we can at least agree that the current methods of generating 
the string arrays at C level are... aesthetically displeasing.

I don't know, I kinda like it ;-)
