Too rapid charging or discharging of Lithium batteries has been the source of real problems for manufacturers. I am sure that the warnings you mention are something the legal staff would be insisting on. Prudent users should have no real problems unless there is some failure of the protection circuits.

Li batteries don't suffer from the memory effect, so frequently "topping off"
the batteries in not a problem. One thing to keep in mind though is that all batteries (available for users) have their lifetimes shortened by internal heating during charging, the more current used (to shorten the charging time) the more rapidly the batteries are damaged and wear out. This is true for Li batteries, as well. So, using a low power charger will take longer but your batteries will last longer. I often use a 500mw USB charger and my USB charged devices aren't taking that long to charge.

Luck;
