Why is that , are you talking the new version ? what changed exactly because I read the changelog and I honestly didn't understand much , too much technical stuff .
The new Bitcoin Core version (0.12.0) enables you to run a wallet in pruned mode. This means that you can use it without storing the whole blockchain. Essentially it can cut down the usage from around 60 GB of data to around ~2 GB.
You only store the last X amount of blocks. thats not what the original version of what prune mode was envisioned.
the original vision was to no longer keep spent data. but keep every unspent
now all of a sudden 2500 people who regularly upgrade are no longer going to hold full data should they enable lite node(which core wrongly calls prune)..
it should be called trim mode.. any gardener can explain the difference
pruning only cutting off the dead parts that are not needed.
trimming cutting off larger areas to improve asthetics and space for growth
but just keeping recent relay data is like cutting off the tree and only keeping the ripe fruit.. good old blockstream adding features to dilute the population of REAL FULL nodes. and leaving the community with a patch work of litenodes and compatible nodes.
if people dont have full history of unspents. then they cannot validate that a transaction is authentic.
why oh why do people think that making full node clients into crippled versions is a good thing. because fundamentally its not. if you want lite clients then download a lite client
stop trying to advertise that running in lite mode is better then sliced bread. if you want to say your a full node then dont cripple yourself or believe your still a full node after enabling such features
if your going to run (better to call it trim/lite) mode atleast accept your just a relay node and not a full archival node
