Those are all disassemblies, not the original code (although the original code for 6809 BASIC was recently found, see https://github.com/davidlinsley/DragonBasic). Similarly, the blog post links a version of 6502 BASIC by Michael Steil on Github that's set up to build the ROMs for a variety of processors, but that appears to be based on a disassembly rather than the original code as well. Here's a random bit of code (the code handling processing a FOR statement) from Microsoft's repo, vs. the same code from Steil's repo: https://github.com/microsoft/BASIC-M6502/blob/main/m6502.asm... https://github.com/mist64/msbasic/blob/master/flow1.s#L3

I'd say it's definitely weird for a standalone assembler. For standalone 6502 assemblers, some approximation of the standard MOS-type syntax has always been near-universal. Though you're quite correct about some of the advantages of doing it this way.
(I say "near universal", because Acorn's MASM had a similar syntax. (See, e.g., https://github.com/stardot/AcornDmosBasic/blob/master/src/DB...) I don't remember ever seeing that described as anything other than an oddity.)
And, also, there are probably assemblers smooshed into Forth or Lisp (or implemented with assembler macros for an assembler targeting some completely unrelated CPU) that work in a similar way, because you're limited by the pre-existing syntax rules. But that feels like a separate category

DragonBasic
This repository contains the source code for the Dragon 64 versions of the Microsoft 16K BASIC Interpreter for the Motorola 6809 (aka BASIC-69 and Extended Color BASIC).
Those are all disassemblies, not the original code (although the original code for 6809 BASIC was recently found, see https://github.com/davidlinsley/DragonBasic). Similarly, the blog post links a version of 6502 BASIC by Michael Steil on Github that's set up to build the ROMs for a variety of processors, but that appears to be based on a disassembly rather than the original code as well. Here's a random bit of code (the code handling processing a FOR statement) from Microsoft's repo, vs. the same code from Steil's repo: https://github.com/microsoft/BASIC-M6502/blob/main/m6502.asm... https://github.com/mist64/msbasic/blob/master/flow1.s#L3

100%.
3 years ago I modified his 6502 breadboard project and added a keyboard, mouse and then I modified MS Basic to get it to run. Also, I found a way to extend the RAM to 31kb. I called it eater-one.
All of his videos and kits are a must if you never understood how a cpu works. I highly recommend them!

They have already released GW BASIC before:
https://github.com/microsoft/GW-BASIC
So I think it's likely that more will follow.
