This used to be how T4T shared their ongoing work. I seem to recall that it did slow down S/R, but that was in PNG with limited internet. I don't know how it would work in a better internet situation.
They ended up switching to publishing it as a resource, which could be downloaded/updated through the Download/Install resources menu. I think that helped. But I'm not sure how widely you want to distribute it (you can restrict access for a resource to specific organizations or sub-organizations).
