A tool that would record the following:

• *IDN?
• *OPT?
• connectivity details: e.g. for Ethernet: whether it can use raw TCP/IP sockets or requires VXI-11
• for Siglent scopes: a dump of "C0: WF? DESC" to see if there are any differences between versions
• any other kind of SCPI commands that can be used to figure out the capabilities of a scope
• which scopes of what brand are actually based on scopes on another brand (Siglent <> LeCroy)

That data returned by such a tool would be useful for developers to avoid making assumptions about a brand of scope that aren't universal for that brand etc.
