"would you tell Eurocontrol?".
When you are over 2 tons you develop this symbiotic relationship with NATS at Gatwick and report every flight. I have developed a simple Excel spreadsheet and fax them a copy of the salient details. VFR or IFR
One does not mess with Eurocontrol! They have a habit of charging every flight given the slightest opportunity. Irrespective, flights are automatically reported to NATS and Eurocontrol via ATC and trying to gain a Eurocontrol credit for an incorrectly billed flight - is pedantry incarnate. NATS can simplify the procedure and liase with Eurocontrol over raising the correct charge.
Now if one dips a tiny toe in cloud during the flight ... a rhetorical question..... I presume........
I have taken pireps from ATC - "aircraft passing your level reports severe icing/mountain wave/moderate chop" - several times. Manch are good at this and London Mil.
Now - doing something constructive with these reports is another question
