Just "worry" about setting the bleed how they want. If they are like the vast majority of publishers and print establishments, they are not going to actually use your crop marks, info, etc., that you set in the PDF. It gets stripped at the bleed amount and the imposition software uses its own marks and info. That's what I do as well in my imposition software with client files and did even back in the 1990s when working in pre-press.

Even when I have gotten files with an excessive amount of bleed, I clip it at what my press sheets need for efficient imposition. And if I get a PDF from a good client that doesn't have bleed but needs bled elements, if those are simple elements, I use pdfToolbox to add it in and repeat the bled elements. (Else I have them submit a new PDF...)
