Master and slave

[Spongebob]

Perhaps a good metric to determine if a word with negative historical connotations needs to be dropped would be when a significant number of people start objecting to it. So far, I’m unaware of people being offended by master/slave cylinders in brake systems, or master suites re bedrooms.

That is totally reasonable and pretty much how it works as far as I can tell.  A tiny group of people aren't likely to change many minds. What typically happens is that a group of people raise the awareness and other people who understand their reasoning join in whether it affect them directly or not.
