For readability. Compare to Cyrillic, where lowercase letters are basically half-height uppercase letters, so everything looks like it's rendered in small caps (this is more true for handprinted lettering, but mostly true for typeset stuff too).

Probably true for Russian cyrillic alphabet tradition but not so much for Bulgarian and other cyrillic ancestry where lowercase letters differ almost for every letter with few exceptions, no matter if handwritten, cursive, italic or normal.

It's why God invented cursive.
