Denmark more or less gave up minelaying when the Absalons were built, & is now reintroducing it via modular systems that can be put on multiple ship classes, including OPVs & coastguard vessels. I don't think it was ever the primary role of Absalon & his brother. IIRC Danish minelaying capability was traditionally deliberately dispersed, so mines could be laid quickly in multiple locations around their islands even while under attack, & concentrating it in two major, long-range, warships doesn't fit that.
Equipped to carry a modular hospital in the flex deck, & the Danish navy has one for that function. Equipped for low intensity operations, including as a command ship - & done that, e.g. against Somali pirates, for which they seem to have been very well suited. Those & other capabilities were designed in, & some have been used.
They were labelled as "flexible" from the start, & their use has reflected that.
