corner, supplies, provides are informations from elf files, so if a lef parser for these can helps a lot for collecting such informations, making tech plugin less bugs.

Corners and supply info come from libs, not lefs, but I agree this info is useful to auto-parse. However, there have been numerous discussions on the topic and the reason we haven't supported it yet is that there are many edge cases that make such a parser a pain to write. I think we ended up deciding that the "right" solution is to have a way to parse the info out and emit hammer IR. A LEF parser already exists here: https://github.com/ucb-bar/hammer/blob/master/src/hammer-vlsi/hammer_utils/lef_utils.py
