This tag exists: soho. Nothing asked in this tag will ever be on topic (and there is only one question in it that isn't either already closed or about to be). Assuredly it should be abolished?
There are currently 13 questions tagged with soho - I don't see any singletons.
Feel free to untag them. The tag will be eaten by the grues if left empty in the darkness long enough :-)
I see absolutely nothing wrong with the SOHO tag. It's a standard term and while the Home Office portion will almost likely be off topic, the Small Office portion could be very much on topic following the standard provisions that the person who is asking is an IT Professional.
Depending on the business, offices in the SOHO category do employ IT Professionals; whether in a full time roll or on a consultancy / outsourced basis. And, additionally, it's not unreasonable to imagine differing requirements for a SOHO vs an Enterprise. That doesn't have to mean crap or cheap, just different!
