I thought the fun of emulation is to emulate something, to do neither more nor less. I don't know when the last VT100 was manufactured but its specification is no longer capable of change. The termcap file is quite specific what a terminal eg. a VT100 can and cannot do.
I don't think there are many terminal emulators left that emulate a VT-100 strictly. Most add some features a VT-100 didn't have (e.g., ANSI color, Unicode) and leave out some stuff that is rarely used or hard to implement (double-height mode, application-controlled keyboard LEDs, 132-column mode, etc.) Generally they're actually "emulating" some cross between a VT-100 and an ANSI terminal, or a VT-100 and an xterm.
Actually, the most thorough VT-100 emulator I can remember ever using was the old MacOS serial terminal program Red Ryder. It *did* emulate double-height mode and keyboard LEDs, the latter via a pop-up window.
