I don't know if this script has been discussed before .. but I love it!
You can find it under create> logo> blending

I remember the logo

Cool logo.
In my 2.10.12 there are no logos under create and in my 2.10.20 I think there is only one under create > gimpchat > BRL logo.
Unless people have added them themselves I don't think there are any in 2.10 unfortunately. There use to be a whole lot in filters alpha to logo too and they were mostly taken out too.

You can download it above .. so you have to add it yourself.
I am using it in Gimp 2.10.20 but also in 2.8 and it works fine
