The spin presets are quite nice, but after discussing the Tetra-X Mini T-spin issue (#626), one could wish to set for example immobile T-spins to go together with Tetra-X or ASC.
None of the current presets currently allow immobile T-spins, even in All Spins the T piece is treated specially and uses a 3-corner check.
Describe the solution you'd like
Decouple spin detection from allowed spins.
After the suggested change, the "allowed spins" would only change the pieces spins could be performed and how much attack they send.
Allowed spins
T-spins: only T piece
Handheld: T piece with 2 attack per line, L, J, Z, S pieces with 1 attack per line, O and I can't spin.
All-spin: Every piece.
Spin detection:
4-point (or 3-corner)
Immobile
EZ-Immobile (new, would function like in Nullpomino)
Stupid
So the current options would become recreatable via these combinations:
T-spins: T-spins + 4-point
All spins: All-spin + Immobile (T would become immobile too)
Handheld: Handheld + 4-point
Stupid: All-spin + Stupid
For All-spin + 4-point, there would be Mini spins available (like in Tetris Kentei or Tetris Stardust).
Describe alternatives you've considered
Setting spins via "Allowed spins", however spin detection is coupled with pieces that can spin, so this doesn't offer much flexibility.
Additional context
May be similar to #622, however that issue was closed with a Handheld option being added.
