Please don't make the solution 'Oh, you can just homebrew a race' since that's not easy for everyone, nor is it efficient.

As this threadВ points out, it would have made more sense from the Wizards team to treat the Lineages as add-ons to a base race rather than their own separate thing. Features like a Satyr's Ram and Reveller/Mirthful Leaps or a Firbolg's Powerful Build and Speech of Beast and Leaf should be as valid as any flying speed or languages. I hope that this is being taken into consideration by the D&D Beyond team working on the implementation of lineages. May I suggest that when you choose a lineage, it also asks for a 'base' race in a drop-down menu, so that it can reflect details that should carry over? (such as natural weapons, movement restrictions, carry capacity, etc) I checked to see if there was any way to apply the lineage as described in the book to a centaur character in DnDBeyond, and you cannot. Let's say I have an unusual race that becomes one of these lineages.
