Using Flow templates

I am very happy with the productivity I get when using Vaadin Flow and with the recent theming changes it is much easier to override and adjust CSS settings.
In my project we are using many custom web components and it has been easy to develop them using front-end tools such as VS code.
The next step natural step would be to utilize Flow templates so that all UI views could be maintained and edited with front-end tooling.
I haven’t looked into this much but I directly ran into this issue, , which is a documented limitation.

My question is if it is worth to use templates as of now and what is the roadmap for removing the limitations?
