>>Sulphuric acid will eat your shoes, your trousers, the wooden floor and, eventually, eat away your boiler.
Of course it will, if you use it undiluted and the boiler is left soaking for weeks. I think the board recognises that some care, caution, and responsibility is required to avoid injury and damage.
>>The only reason it's ever recommended is "because that's the way we've always done it".
Or, . . . . if it was discovered long ago that it does its job very well, as well as anything else, is freely available at a reasonable cost, has a long shelf life, and can be safely disposed of.
I wrote what I did based on long experience, having had my shoes, trousers and workshop floor attacked by
dilute sulphuric acid many years ago. Since then, I've always used something a little safer. As for "care, caution and responsibility", I'm still alive and in one piece after a lifetime in industry, so I reckon I know a little about that too.
The old time "experts" were not alway right.
