Why bitcoin has so many different address formats? – Beragampengetahuan

We know bitcoin has at least 4 completely different address formats. They are legacy format, bch32 script, segwit. I know each address format means different transaction types, for example pay to public key hash, pay to script, or segwit payment.

But my question is why not wejust use one kind of address type, such as legacy p2pkh?

By contrary, ethereum and other blockchain has only one address format. Does these blockchains lack some function that must introduce new address formats ?

Or another question, if we only use the original bitcoin address format, aka. the legacy p2pkh. Is it possible to implement other formats’ functions?
