[RFC] Hide 'JUser: :_load: Unable to load user with ID: xxx' warning message

[praneettekdi]

Steps to reproduce the issue

If a user gets deleted from the system and if that particular user had a reference in any other component, then while loading that deleted user, Joomla throws a warning message like JUser: :_load: Unable to load user with ID: xxx which sometimes is not required. And it somehow disturbs the UX.

Expected result

Of course, there is a workaround using SQL queries, but by default, there should be a way to hide such messages.

Actual result

Shows warning message: JUser: :_load: Unable to load user with ID: xxx

See discussion in #20689 , please.
And resulting "fix" for Joomla 4 which is only a change of the used language string. #24166

BTW: I personally still think that the alert message is a welcome thing in backend.

The changed message is good.. However as suggested in this issue https://issues.joomla.org/tracker/joomla-cms/20689 we should only show this - say if Debug is on.. As while it could be useful to administrators showing this in the frontend might not be a good idea even if the message is changed. I think the use case here is that the JUser object is being used to load things like the Usernmame/Name instead of doing direct queries.

I think such messages should not be show, but logged instead. There also some errors in file-system classes doing similar stuff.

Showing the error for users only makes them think that the site is broken.

Many commercial templates have that issue at least (but not only) when one deletes the pre-configured users.
