That was a weird comment.
I'd say no stuff is OK with a VT100 if they expect a VT52. As soon as we 
go outside the plain "output running text", they are different.

That said, a real VT100 can be switched into VT52-emulation, which is 
pretty good, although not exactly identical.

In this case, the poster even was nice enough to tell what the problem 
was. A VT52 will display a block character when you send a DEL to it. A 
VT100 will not, not even in VT52-mode. And I don't think any other 
VT52-emulation I've seen does it either.

In fact, I don't even know if a real VT52 do that. It might be a 
"feature" of some russian VT52-clone for all I know.
I haven't had a working VT52 near me in 15 years now, so I can't check.
