If you agree with a comment, usual convention to save everyone time is
don't reply to it and ideally crop that part of the email out entirely.
It is hard to find the active discussions that need replies in an
email unless it is cropped to make them the only remaining parts.

This discussion has been had many times and the standard approach to this has
changed over time (in IIO anyway). We have not yet updated all drivers to
the current policy.
Current policy is that we do not block probing a chip that firmware has told
us is compatible on the basis of a failure to match a chip id.
Print a message to help with any bug report issues you may get.
+ educate integrators of your device that they must not put false compatibles
in their firmware.
