The replacements tag (and the replace tag) don't have a tag wiki, and I'm wondering how they're meant to be used. Are they supposed to be used on questions on how to replace things? Are those even needed?
I find these tags are being used in the following ways:
- Indication that a replacement occurred (circumstantial clarification)
- Request for instruction on how to replace (used in the verb sense here)
- Assessment of the suitability/compatibility of replacement parts
I don't think the first two use cases warrant a separate tag; the latter can be covered by a more specific categorization such as compatibility (which isn't used enough by the look of things).
