Server Boosting - Let Boosting Badge Stay (Last Badge)

I know nobody will read this or take this serious but hey, why not!

Imagine that 24 months or 2 years have passed and you have continuously strengthened one/several servers during this time. 

For example, you boosted any server continuously for 30 months. You have now decided to cancel your boost; technically this means the "Boosting Badge" will be deleted from your profile. Normally this isn't unreasonable, but losing the badge after paying boost for as long as 24 months / 2 years would be heartbreaking. 

So my suggestion is that ONLY THOSE WHO HAVE THE LAST BOOSTING BADGE should not lose their badge when they stop boosting. It's okay to add a new badge; It could be a badge like "Senior Booster'' or ‘’Veteran Booster''. It wouldn't be bad if those who have this badge received a small discount like 10% or 5% when buying boost from now on, but this is just my suggestion.
