When the first param of (s)printf is a literal string (otherwise not possible to validate in psalm):

https://psalm.dev/r/7749cadcab

• for %d (or %1$d) the corresponding param must be type int (as string will be returned as 0 and float as int)
• this applies not only to "d" but to [bcdouxX]
• if placeholder is any of [eEfFgGhH] type should be float
• if placeholder is s should be type string (if we want to be less strict allow int|float|string like now)

Would be the next step after #9817
