chore: random todos (#15541)

closes #<!-- Add the related issue number here. Repeat this line for
each additional issue it closes -->

<!-- Explain the goal of the PR, why it is needed, and what has been
changed to achieve that goal -->

---

### Please don't delete this checklist! Before submitting the PR, please
make sure you do the following:
- [ ] It's really useful if your PR references an issue where it is
discussed ahead of time. In many cases, features are absent for a
reason. For large changes, please create an RFC:
https://github.com/sveltejs/rfcs
- [ ] This message body should clearly illustrate what problems it
solves.
- [ ] Ideally, include a test that fails without this PR but passes with
it.

### Tests
- [ ] Run the tests with `pnpm test` and lint the project with `pnpm
lint` and `pnpm check`

### Changesets
- [ ] If your PR makes a change that should be noted in one or more
packages' changelogs, generate a changeset by running `pnpm changeset`
and following the prompts. Changesets that add features should be
`minor` and those that fix bugs should be `patch`. Please prefix
changeset messages with `feat:`, `fix:`, or `chore:`.

### Edits

- [ ] Please ensure that 'Allow edits from maintainers' is checked. PRs
without this option may be closed.
