I might be able to help you in part.

90.1-2019 has addenda: Addenda af, bc, cd, and db to Standard 90.1-2019 (November 16, 2020). Same as 90.1-2022.

For 90.1-2016, I couldn't find similar addenda. Personally, I would model the additional lighting power in the Baseline case in the same way as 90.1-2022 and 90.1-2016 addenda. I often refer to the PNNL guide, but it could be incorrect as PNNL have never issued any errata or adddenda to the guide.

SUPPLEMENT

Regarding your comment, below is the comparison of different versions.

I only have SI units versions in hand, so my conversion from W/sqm to W/sqf might be a bit inaccurate, but the table is enough to trace the transition. The additional lighting power allowance has been gradually reduced. The allowance for 90.1-2022 makes sense to me.
