This tag is redundant, as [sd-card] exists. There aren't many things specific to micro SD cards that aren't shared traits with SD cards.
People may not have responded to the question due to the solution presented in the question not being seen as desirable, even if some type of action seems warranted. I'll post an answer to bump the issue with another solution people can react to.
There is a trade-off here.
- It is helpful to have separate tags consistent with the terms people use to think about their problem.
- Aside from that, the only practical difference between the form-factors that would affect answers here is the lack of a locking switch on the micro-SD format. Keeping the two tags separate hides useful solutions on the other tag, or encourages people to double tag.
Synonyms are the mechanism available for linking multiple intuitive tags to the same content. SD Card is the more generic term. Let's make micro-sd-card a synonym of sd-card, and expand the wiki and excerpt to clarify that the tag applies to both formats.
For that matter, we could probably make it even more generic and make it applicable to any form-factor of a generally similar flash memory card (comment on preferences regarding this last point).
