RD 5600 compatibility on 11-28 cogs?
Currently using a 12-27 T for my RD5600 10 speed. However, I’ve read on shimanos spec sheet that this RD is only rated for max 27T. Will I have an issue fitting a 28T on this?

hmm even when I’m busting shimano’s specs? Will my rear D be stretched with just one extra tooth?

Why do you ask if you don't want to believe the answer?
Shimano is conservative in their spec's because their "stuff" has to work with a variety of different bike manfs. that may not all have the same hanger geometry etc.
Typically, you're good for a couple extra teeth.
Your wrap capacity might not be adequate, depending on what rings you have on front, so with a properly sized chain, it may sag in the LOW:LOW. Since you shouldn't be using that combination.....

I have this exact setup on my 2006 Lemond Tourmalet. The bike originally had a 12-25 rear cassette using a RD5600. I swapped to an 11-28 cassette and have had no issues. FWIW, I have a 52/39/30 triple front setup.
