1. Workarounds are too long
   
2. Scratch Jr has it
   
3. Good if you don't want to use too many clones or/and even reach 300 limit (eg. particle system and clones)
   

• as stated in OP (long chain of blocks)
  
• make list of every sprite and make code to check if it touches anything from the list
  

<key [any v] pressed?>
when [any v] key pressed

In most cases a ‘touching any sprite?’ condition would be too general. E.G. you want to detect walls during collision and enemies during damage detection but not both at the same time.

<<touching (any sprite v) ?> and <not <touching (enemies v) ?>>>

<touching [any sprite v] ?>
(sprites touching :: sensing)
(distance to [nearest sprite v])
(distance to [farthest sprite v])
(distance to x: [0], y: [0] :: sensing)
(2 nearest sprites :: sensing)

I support. This would be useful. Also, remove the supporters list from the OP, it's not really necessary.
