bitcoins use case has change
this is because things called OPCODES change the use case of a transaction. whereby it changes how much data can be contained in a transaction. how much of that data is even validated/accounted/counted. and other things.
when new opcode subsets are released changing the bitcoin rules via softening the rules.. it changes how bitcoin is used.
starting with allowing 4mb of unvalidated, miscounted junk to be appended to a tx that has no functional utility of signing proof of the sats intended to be moved, but sit at the end of tx for nonsense unrelated purpose to bitcoin functionality, which most bitcoin nodes dont even check the content of such added data ..
bitcoin code(rules) were strong years ago, where every byte had purpose and was counted and checked to meet the rules..
devs used to care about every bit and byte. and want efficiency...
now devs want congestion and miscounting of bytes and inclusion of bytes that have no purpose
the whole softening of the rules in the last 7 years has not helped bitcoin. but has just helped dev politics do as they please even at the annoyances of bitcoiners..
Yes, you are correct that Bitcoin's use case has evolved over time due to changes in opcode rules. Opcodes enable the execution of specific operations within a Bitcoin transaction. When new opcode subsets are released, it can modify the rules of Bitcoin by allowing for different data sizes and validation processes.
The introduction of new opcodes can increase the data capacity of a transaction, allowing for the inclusion of additional information that may not be directly related to the intended purpose of the transaction. While some Bitcoin nodes may not validate or analyze the content of such added data, it still becomes a part of the transaction.
