Capitalisation and hyphenation of final element of <id>

[ColinKinloch]

Most packages on flathub capitalise the final element of a .

The specification seems to suggest that hyphens are acceptable in the final element https://www.freedesktop.org/software/appstream/docs/chap-Metadata.html#tag-id-generic

This creator takes "Celestia-qt6" and "https://celestiaproject.space" and produces: <id>space.celestiaproject.celestia_qt6</id>

Should I should change every instance of the id to space.celestiaproject.celestia_qt6 or is space.celestiaproject.Celestia-qt6 is acceptable in the metainfo file?
