Hi @demoncoder-crypto

Thanks so much for the PR! I'm not sure if this is something we're likely to merge. If I understand the changes correctly, this is updating the default behavior of some of our themes and styles for M3 and MaterialComponents which would likely break existing usages. Additionally, our design guidelines call out using a collapsing toolbar for multi-line titles and suggests avoiding wrapping title text in a standard Toolbar.

Have you considered using a CollapsingToolbarLayout inside an AppBarLayout when titles might be multiline (which we support). You can see an example of how to set this up in our TopAppBarCollapsingMultilineDemoFragment example. Here's what that looks like:

Closing this for now but feel free to re-open if you'd like to continue discussing the changes.
