It’s more painful than positional. To me the fact that everyone who works on code bases that are of non-trivial size see positional arguments being used for calls with more than 3 arguments is a pretty obvious proof. I know I write them myself because it’s nicer even though you’ll have a hard time finding someone who is more of a proponent for kwargs everywhere than me! 

I feel this pain daily. You aren’t me so you can’t say if I feel this or not.

If you don't have the inclination to reconsider the design, it could be nice to create a standard code pattern for these pass-through functions to make them more beautiful.

Not talking about those. But I agree that fixing those might be a good first step. Unless it hinders the progress of the bigger issue of course. 

I’ll repeat myself: what about .format()? If you localize you can’t use f-strings. What about templates in web apps? Obviously f-strings won’t do. What about json blobs in REST APIs? Again no help from f-strings. What about functions with more than 3 arguments generally?
