It will be better if the If Blocks were renamed the “When Blocks”
Here's what the blocks will look like

when <> then
end

when <> then 

  

else
end

Do you agree?

No support. When New Scratchers look at an

if <> :: control
end 

block, they know exactly what it does: it will check a condition, if it's true then the code inside the block would run, if it's false it would skip.
If they looked at a

when <> {
} :: control

block, they would think that it would wait for the condition to be true.

Fun fact: there used to be a block of the same name in an early version of Scratch, but it was removed because it was glitchy.

when <> :: hat control

No support.
It would be more confusing. “If” is a conditional word in English, so is the block. “When” is a conjunction, and in programming, it indicates that something starts, not happens if something is true or false at any point at any time.

In addition, “if” is the keyword used in effectively all other programming languages, so it's best to minimize the differences between Scratch and those languages to make the transition between them smoother.

Eh, I feel like “if (…) then” is intuitive enough to understand, and I don't see much point in renaming it: especially as “if (…)” is used in pretty much every language (as @Sheep_maker pointed out).

No support. Nearly early every other programming language uses if, not when. If is also fairly intuitive imo.

As @discussion_man said, majority of programming languages use the “if” statements, and like the others above said, “if” and “when” are different commands. It's important to keep it as “if” so people can go on to learn more advanced languages and see familiar code.

So, No support
