Role playing games do not enforce role playing, they just give the opportunity to do so. But its the player who choses if you care about playing a role and what kind of role you play.
The devs create the rules for the game and I have the this opinion:
Everything is allowed as long as it is possible to do such a thing and there is no rule that says its forbidden.
So yes, its totally OK when your paladin summons undead, the priest of light has darkness as his fovourite spell and the rogue backstabs enemies with a ballista.
In a computer game the devs program the rules and everything that is possible is also allowed.
In a PnP game the GM has the final word what is possible.
The devs should discuss with the players what rules make sense ( thats what this forum is good for), but in the end its the devs who make the rules however they want.
Its up to the player to decide what role to play and how to play it.
And now let me role play my warlock/paladin who uses charisma for spells and weapons and with his holy weapon he adds both radient and necrotic damage to his attacks while summoning undead as meat shield and having ultra high saves and immunity to several effects.
