I agree that some of the limitations of the original 8-bit PIC instruction set are a pain. However, they fixed several irritations when they did the 2012 upgrade to the "enhanced" 16F1xxx chips, and I now pretty much only use the newer chips.

I wrote to the list about these chips at the time, 12 April 2012; "New 16F18xx enhanced mid range PICs"

It's certainly possible to program the 8-bit PIC in assembly, but I wouldn't recommend 100% assembly as it certainly can be a pain to deal with the limitations (4K RAM in 16 banks, etc).
