How does Python or _javascript_ manage with their map implementations that use a hash to select a bucket?

One would want a low collision hash and that's really all that's needed to make unique filenames from input data that would be too long to just concatenate.

Follow-up Comment #3, bug #61594 (project make):

To add my concern regarding integrating cryptographic hashes into GNU Make
relate specifically to import restrictions of some of these hashes to a large
number of countries. Searching on Cryptographic Import Restrictions will
explain this. Having user selectable hashes through the load function would
decouple any restrictions that would otherwise be imposed and limit the
ability to use GNU Make; however, I would caution that using these functions
in Open Source projects would transitively limit or confuse the ability to
build those projects if the hash functions are unknown or not available.
