update package if previous upload dropped out of testing

Hello list

The developers of markdown syntax checker markdownlint published a new version 0.17.0 for which I would like to provide an update to `ruby-mdl`.[1]  Meanywhile, my previous upload to Debian was version 0.15.0 which however dropped out of `testing` because of its dependency `ruby-mixlib-shellout` explicitly mentioned in d/control itself dropped out (which however dropped out because of `ruby-chef-utils`).

This is the first time I encounter the coincidence of the two states "a dependency dropped out" and "time for an update".  Because I'm a sponsored maintainer of `ruby-mdl`, I would like to ask in advance if either

- I already should prepare (on salsa) an update, and file a RFS for then updated version 0.17.0 of `ruby-mdl`, or
- it were better to wait for dependencies `ruby-chef-utils` / `ruby-mix-shellout` to return as functional in `testing`, and then commence the update of `ruby-mdl` on my side.

Best regards,
Norwid
