We had TECO on our DEC VAXes running VMS in the early-mid 1980s. It had a ”VT52” mode (as you say, a macro), and at least one of the terminals on my desk supported those escape sequences. Wikipedia says the VT52 terminal was made from 1975 to 1978, so those macros were probably fairly early. By this stage, TECO distribution was fragmented with various incompatible versions around, so probably some lacked that macro or other full-screen macros.
Although I had a terminal which could run TECO full screen, I found that too slow and just used it in line mode. You could conveniently reprint surrounding lines by adding a few characters to the end of a commmand (I still have HT <ESC> <ESC> burned into my brain.) The VT52 macro had you typing commands into line 24 like an emacs minibuffer.
I never used it for all my editing, but it excelled at certain things.
The version of TECO we had was the one which shipped with VMS. At some point later on, I think, DEC stopped shipping it, and we migrated to a TECO-inspired full-screen editor developed by another university. Once that arrived, we hard-core TECO users, all 4 of us, were won over within a week.
