Even so, I’m not sure this is something that the developer is going to want to add to ACF, at least not in a hurry. If this is something you need right away I’d suggest looking into making it happen.
For an example of something similar take a look at this topic that has several example of updating term_meta and retrieving the values. This is something that others worked on until the developer figures out how to implement term meta in ACF https://support.advancedcustomfields.com/forums/topic/how-to-use-wp-term-meta-on-acf-the-easy-way/.
