Make cake's locked period ability to be much higher so people gift it as an investment to their loved ones.

So now every year once the locked period ends the cake has to be renewed and this creates a bit of a problem especially if one wants to gift a staked cake to their loved ones. So I want to be able to stake cake indefinetly unless I order it to not autorenew. This will be good so people will be able to gift cake to their loved ones for example to a child who is 5 years old to gift it and tell him to use that cake when he turns 22 so within 17 years. Of course to expect that he will auto renew every year is a bit hard so auto renew function will make cake attractive to become a have to gift for every birthday. Probably infinite locked period won't be good but for 25 years auto renewals should be enough. P.S If idea is good I'll be glad to be rewarded acordingly.
