If you’re going to give praise, include the GNU Fortran developers, who have really set the standard for open source production quality Fortran compiler development.
The only times I set foot in the Fortran world is when some Julia-related development [1] [2] happens, and then I peruse some surrounding links and related projects - so I have very little familiarity with GNU Fortran myself.

[2] "in recent years" because that's when I became aware of this stuff, not to say there wasn't effort before then
