There isn't really an elegant way of avoiding that. What probably does
want doing for a final merge is to make them more generic. So that
anything can be a source or a sink that meets a basic interface.

Then you'd be able to do

set ldisc to tracesink
ioctl (something or other) "attach to sink of
name 'modem/mipi/p1149.7'

or similar.

That would need a struct of some sort and a register_sink/unregister_sink
method. Ditto for tracerouter. Obviously for now only the current drivers
would support it but the interface is then there for anything else
