Question about ElGamal for homomorphic encryption

[jtovartr]

I have seen in the official documentation the following information about ElGamal:

Even though ElGamal algorithms are in theory reasonably secure, in practice there are no real good reasons to prefer them to RSA instead.

I want to use ElGamal for homomorphic encryption, why can this algorithm no longer be used?

Since I can't use ElGamal, any advice on how to perform homomorphic encryption?

Thanks

Of course you are free to use it, but this implementation is purely there for backward compatibility only, not to support applications needed real homomorphic encryption.
