Things like this have been around for nearly (at least?) 10 years, but are not well-known outside of spaces that care about telco-style demarc & OAM systems.
An example from ~2012 would be the RAD MiNID which is available in a handy "sleeve" format where you can use your normal SFP with the smart SFP.
Pretty cool to see a writeup of this sort of thing (and increased vendor representation).
