Not for me! With a teabag, longer = stronger = harsher. For me, this is the perfect example of excessive tannin extraction. Difficult to do with a mash in my experience, so easy with tea (at least, with the English version of Indian tea in teabags Tetley, Yorkshire etc)
I've had no problems leaving my beer to mature with dry hops. But, I reckon do not leave it on a sediment that includes dead yeast for more than a week. In my experience, you will get off-flavours. Slight at first maybe. You might not notice them - but I rack my beer off any thick sediment & I'm certain the flavour is cleaner & better.
Oooh! now that's (racking to a secondary) a dark and twisty mine field with plently of conflicting opinions if you've a mind to google 'rack to secondary'
