Any reason why it is such a bad idea, why is it not possible to install all of those plugins.
And I could simply put each of them on a - sudo -E -u discourse git clone line and do it that way.
What would be a more time efficient way, saying as if I theoretically really wanted all of the plugins.
You’re introducing a lot of risk by installing that many plugins. You can run into performance issues, incompatibility issues, security issues, some of those plugins have redundant functionality… when you’re installing plugins you should have some general idea of what it does and who maintains it.
We don’t allow third-party plugins on our official hosting without closely reviewing the code, for example… because we need to closely manage the security and performance of our servers.
