Subreports in footer - definitive answer needed

[darth_fader]

I've seen mixed answers on the subject, so I'm hoping an authority on the project will chime in: can we safely use subreports in page footer bands? My scenario is branding: I want to brand the footer with organization metadata, and just like with html, the footer content is redundant for most/all of my reports.  Subreports are the closest I can come to templating in jasper. 

I've tested and it seems to be stable, I'm just wondering if there are any issues that could arise that I'm not aware of? This particular subreport has a real query with fields etc, but there is a one record limit and fields associated with that record will always be displayed in two lines - in essence it's a fixed height. I can see how issues would arise if we tried to put a standard detail band with page after page in the footer region. But this is not the case.

I'd also like to take the same approach with the page header, so a better way to ask this question may be, "Are there report bands we should avoid using sub reports in"?

Thanks
