This is a follow up review to prior -08 version ~3y back.  Prior review
comments were addressed and it looks good from a YD standpoint.  Only a few
minor questions/clarifications below.

1 module in this draft:
- ietf-bfd-stability@2024-05-05.yang

YANG compiler errors or warnings (pyang 2.6.0, yanglint 2.2.8)
- No compiler errors or warnings

Module ietf-bfd-stability@2024-05-05.yang:
- I notice between -08 and -13 that `micro-bfd-ipv6` augments are now removed.
  Is this intentional?
- For all augments that introduce the `lost-packet-count` leaf, these are all
  identical definitions which could leverage a single grouping/uses
  definition.  Any reason not to leverage?
