I spun this topic off from Interactive fiction popularity metrics:
I analysed the spreadsheet a little to identify development systems that have been used exactly once:
Summary

Haskell TAE
Hyperfable
Inquisitor
Instead
IntFicPy

TIC-80
NOTES:
C VARIANTS
There was a C# game listed, and a C++ one. And while the TIC-80 (a tiny modern computer system I’ve left in the list) is programmed in C, it probably has hardware-specificity that makes it unique, so I kept the TIC-80 in the list. It’s also possible a game in the spreadsheet labelled ‘custom msdos’ could be C, though it’s probably a variant of BASIC. The upshot is, at least three variants of C have been used in total, and two in a hardware-independent way, so I’m not paying the C variants as development platforms that have been used only once.
BASIC VARIANTS
I took the same approach towards flavours of BASIC. Multiple variants of MS-DOS BASIC have been used and listed in the spreadsheet (the majority of the games by Paul Panks) so I’m not paying them as one-shots. In the hardware-specific BASICs, my game Leadlight is the only one in Applesoft, and it looks like Nick Montfort’s Amazing Quest is the only one in C64 BASIC. I thought Paul Panks might have submitted a C64 game, but I think his IFComp entries were all MS-DOS.
PYTHON VARIANTS - DANCE?
Python has been used several times in IFComp and so doesn’t make the list per se, but things get grey. IntFicPy is a specific engine within Python that’s been used once, but could be used again, so I kept it. Jupyter Notebook - is that just Python? Does the hardware make a difference? I don’t know enough to kick it off the list.
One game with platform development ‘Dance’ is listed in the spreadsheet: War of the Willows. I know that ran in Python, so I don’t know if Dance is a Python toolkit (I couldn’t google it up) or a joke or mis-paste. Someone can probably tell me.
THE MORAL OF THIS STORY
You could be unpopular, too! Just use a new and unique development system for your IFComp entry. Or, make yourself unpopular with the author of a game in this list by knocking their game out of this list by being the second person to enter a game into IFComp using the same system they used.
