Ok. Let's create an example. Bloggs didn't fly at all in the first year, then did his 12hours etc. etc. in the first 3 months of the second year. How much longer than the end of the second year would you suggest he should be able to revalidate without an LPC?
I can see the OPs point - you could get it signed "in date" and do exactly the same flying as in your example no matter how long you left it beyond the second year, but the UK CAA are interpreting it in one way and the Danish differently - if you don't like the way the UK does it go to Denmark and get it signed there - it will of course probabaly cost more to get the flights to get it signed than an LPC in the UK.
