Absolutely. For my workflow, the XCF requirement and the need to manually export were completely wrong. In the 23 years I've used it, I've never once needed the XCF file format. I acknowledge that others will need it, but I don't, and the change to the workflow made it significantly less usable for me.
This again comes back to the project management and project goals. There is very clearly a desired workflow and feature set that users are expected to use, and deviations from this workflow are not desired or well supported, and accommodations for non-standard workflows are not well received.
As a minor developer of open-source software, I've always been surprised at the diverse range of uses people have attempted with my software. Often things I'd never considered. In most cases, I tried to accommodate these uses so long as they could fit within the application design, and occasionally with some refactoring to fit them in. Because in most cases this was of net benefit to the application, widening its appeal and usability, and driving cleanup of the architecture to make it more flexible and more amenable to extension.
The unwillingness of the GIMP developers to support fairly basic vector and path operations speaks volumes. There's clearly a demand for it. They would be self-contained and not have any major impact upon the wider application. And yet, they have been repeatedly rejected. If I was the maintainer, I'd have considered and allowed their addition. But it seems that the GIMP developers do not want to expand the remit of their application, even if it would be of net benefit.
