Update!
Hiding repair recipes works with PR #558
it's unlikely that any of the steams' tags will be altered, at least in the short term. Systeams' Steam is generated by all boilers, NC:N's steams' applications are still in flux and therefore won't be touched for a while. GT's steam is obviously not going to be altered due to deep integration with the Steam age.
The only thing of interest about the Steam tag is that TE boilers generate Steam multiple times faster than the singleblock GT boilers, but that'd likely be addressed with a config change rather than a tag change.
Experience is in a similar situation: Soph Storage uses its Experience as the default fluid to generate when storing player XP when using the pump, and Thermal's Insightful Condenser can condense Experience into a fluid from an operating Aquatic Entangler. Since there isn't a way to convert these fluids directly into XP juice, the only way to use them is to convert them back into player experience through Soph Storage's XP pump.
This is all quite jank however, so I made another PR to eliminate all the items involved in #559
Lastly, TE Creosote was pretty simple to remove tags from & hide.
The Create stuff will have to be done by the people managing the compat script, which I won't touch since it's not my thing :/
