Since I did some here mentioned blitter enhancements for Atari ST games (GGS blitter scroll, now Uridium, + couple others) I need to say couple words here.
I did GGS fine scroll first using STE HW scroll capabilities, but it needed some trickery with timers because not whole screen scrolls. Then came idea to use blitter for drawing background on screen - and it did it very fast with all needed shifts for fine scroll. So, no any background preshift was necessary.
And holding many preshifted backgrounds not just takes lot of RAM but makes all it slower when some change on background happens (like destroying some object) - because you need to draw changes on all preshift phases in moment of destroying.
I did all usual (possible ?) ways: there are versions with 4-8-16 preshift phases, and by 8 and 16 phases there is visible slowdown by mentioned background changes. There is special version for TT, where CPU does all shifts during background draw on screen - and it's 32MHz 32 bit CPU with much faster barrel shift matches approx. 8 MHz blitter in speed.

Considering 2 codepaths: I seen solutions with 2 paths in same executable, and solutions where diverse executables were loaded depending on available HW, so no, it must not take extra RAM. Especially if HW depending code section is small in size. And why should some scroll or sprite draw code be large ?

The ST was an OK machine, was never great, it filled a nice gap in the market for being affordable.

There will never be a game like Elf Mania or Lionheart on the ST, even with all the time in the world. Hypotheticals are all very fine but in the end that's all they are. I love the ST, it was my first 16-bit computer, but I realise the machines limits. Can't we just say the ST was a fine machine but will forever live in the Shadow of the Amiga.

Shadow Of The Amiga - Possible game title? Haha!
On EAB we have Galahad and Meynaf porting ST games to Amiga etc, but where are those ST coders patching ST games to add STE features... We win :-)

You might have to return that medal there

As it turns out there are a number of ST->STE 'ports', including R-Type Deluxe ( [ Show youtube player ]), Pacmania (https://youtu.be/07MIDzSEp58) and of course, the recent Atari STE version of Ghouls And Ghosts (https://youtu.be/ZWOHrtpAKlU).

Both platforms have great coders doing great work

Both machine were great and I did and still do own and play with both. Trying to get my hand on a 1040STE to complement my 520STFm, just like I got an A1200 to complement my A500.
