I tend to create sparsebundles to clone my git repos within, to get around the overhead of having huge numbers of inodes on a volume. (Copying, deleting, unpacking archives, Spotlight indexing—all are way slower when you have the worktrees and .git directories from a thousand large repos splayed out across your disk.) So I was a little worried here.
Thankfully, I had manually been setting my sparsebundles back to HFS+ on creation, because I saw no reason to make them APFS containers.
