Speed of pulls is slow. Any way to disable stage collection?

[Erotemic]

I attempted to pull a very small file dvc pull -r aws train_labels.csv.dvc -vvv, and I it took nearly a minute to finish. I added the -vvv to give me a sense as to what was going on, and I noticed a ton of "collecting stages" messages:

You can see the command starts at 21:35:53 and starts "collecting stages" 7 seconds later at 21:36:00,221, it then continues to collect stages for until 21:36:39, nearly 40 seconds later, and then it finally after 4 more seconds.

I don't use DVC for pipelines, I've never used a stage. All I use it for is git-for-data, which it's great for... until I start adding lots of files to a single repo, and then I run into issues like this. Is there anyway to disable these stage checks? I see in #7093 there is an item stop collecting whole DAG all the time in the whole repo, is that related to this?

I added:

        stages = []
        metrics = {}
        plots = {}
        params = {}
        return stages, metrics, plots, params

to short circut _collect_all_from_repo and ran the pull command on the same file on a different machine (i.e. so it needed to do the same steps), and it worked in 6 seconds. This does seem to break -R, but it also shows that collecting the stages isn't necessary and actively hurts one of the best things about DVC.
