In my understanding, AFM and PFM are not essential for the system that can rasterize PS Type1 CharStrings by themselves. PS Type1 CharString has the operators to define metrics (see "Adobe Type1 Font Format", there are "hsbw" and "sbw" operators), PFA & PFB can declare the metrics in each glyph data. The metrics-only files AFM & PFM were introduced for the system that cannot (or want to skip to) rasterize PS Type1 CharStrings but can display bitmap glyph data (obtained from bitmap font or non-native rasterizer) at the positions calculated by metrics-only files. However, it is theoretically possible for AFM & PFM to have the metrics which is different from PFA & PFB. I don't know recent utilization is popular.
