Will MIRO exits generally fire in MR8M also?

Question

In this thread here:
MIRO equivalent of MIGO exit_saplmbmb_001 (or MB_DOCUMENT_BADI)
Krishna Reddygari was kind enough to provide a list of exits and BAdIs related to MIRO.
My question now is:
is it usualy the case that if an exit fires in MIRO, it will also fire in MR8M?
The reason I'm asking is as follows.
Regardless of whether the customer uses MIRO or MR8M, I have to update two custom fields in EKPO line items.
So I'm hoping that the exit or BAdI that I choose for MIRO will also fire in MR8M.

No prob with the points.
If you end up using it, have in mind two things which are not so visible in the documentation:
Note that you must not send any system messages in the methods. One exception to this is the method CHANGE_AT_SAVE. In this method, you can issue a system messages if the exception ERROR_WITH_MESSAGE is triggered simultaneously.
Note: only for non-exit commands: you can check the command type in the SAPLMR1M GUI statuses - DELE for preliminar document deletion is one example - or else you get a dump
The statement Commit Work must not be performed, since this leads to data inconsistencies in the database.
Good luck.
