I realize there's a performance trade-off in for the flexibility such functions provide, but it may be worth investigating cl--position in particular. Today I replaced an instance of cl-remove-duplicates with an equivalent cl-loop for a 15x performance improvement at the cost of 2 lines of code. Not sure why is this a bug report. If cl-position is too slow for your application, you can always use something else, something that is less generic and more tailored to your specific sequence type(s), no?
