Obsolete Named FontSize Values in XAML are Suggested by IntelliSense

[severity:It's more difficult to complete my work]
If you edit a XAML object with a FontSize property the suggested values are strings like "Large", "Medium" and so on. If you use one of these and turn on XAML->CS generation by setting MauiXamlInflator to SourceGen in the project file you get "Obsolete" warnings (see #33466). It looks like the intent was to make named values obsolete as of four years ago (see pull request #5088). With this in mind it seems like a bad idea to have IntelliSense suggesting named sizes.

This issue has been validated in Visual Studio 18.0.0 with MAUI versions 10.0.0 and 10.0.30. IntelliSense suggests string values such as "Large", "Small" and so on. However, when SourceGen is enabled, warnings are shown as below. Therefore, the issue is reproducible.

Sorry for the confusion here, this ticket does in fact belong on the VS Feedback system where you opened it initially. Reopened that one and closing this one.

Thanks, I realized I'd never reported the original lack of a warning in XAML anyway, so I created #33623 just to keep the MAUI bug report count up... 😊
