Plugins need to check if they are loaded?

[Ligustah]

Why do plugins need to check if they are loaded already?
Isn't that a thing general enough for the plugin loader to take care of?
If i am not mistaken all plugins use the very same code to do that check,
so why not put it to a place where it is done for all the plugins automatically?

I'm just trying to make up some reasons that could be behind this, don't take me too seriously

There might be a scenario when actually loading a plugin twice would affect the way the plugin acts. For example a plugin that adds a bot that it controls may add another bot when loaded for the second time. Or a logging plugin might get loaded several times, each time with a different configuration (output file, verbosity, ...)

..you don't really need to check if the plugin is already loaded inside the plugin if you don't want to

I was just wondering about that, because it seemed akward to me that all the plugins
i looked at checked for that in their code.
And it looked all the same.
