While a viable lunar mission might be some years off still, I've noted that the existing lunar-module tag is geared towards Apollo exclusively.
The Lunar Module was part of the Apollo program spacecraft package. It rode into orbit beneath the Command Module and required extraction once there. It consisted of a descent stage (which remained on the Moon after landing) and an ascent stage (to take astronauts back into orbit). Use with the [apollo-program] tag any any appropriate mission tags.
Since everything seems apollo-program related, a simple rename to [apollo-lunar-module] would help us differentiate questions about this pioneering spacecraft from those about upcoming lunar modules/landers
