I would say that as with the auto-imports in general - it is up to you and your personal preference.

It is designed to work like this and I personally like it and use it. Some other ppl would prefer to have explicit imports and then they would also "wrap" them in variables instead of calling them directly.

Sometimes it may be useful to do something like const alias = veryLongAutoImportedMethodNameIDontWantToRepeatDozenTimesInMyTemplate() but I wouldn't make it a law.

Generally it is a good practice to keep the template expressions simple to have them clean and easy to read. Single method call is ok (for me better than creating a variable just for sake of having a variable - which possibly introduce the whole <script setup> section that would otherwise not be needed at all), more complex commands should be moved into script section regardless of the auto-imports themselves.
