ok heres some idea's to satisfy all camps

block hard limit increased to 2mb (allowing for more than 2mb potential for SW lite wallet)

the relay data is by default set to send signatures. even with SW miners. but anyone can if they are SW upgraded, can handshake with their peer to not request signatures as a non-default option. allowing old clients to still have some purpose, (no immediate castrations) while fanboys betatest new implementations live. and review if the masses should upgrade afterwards

miners drop the tx fee back down to 0.00001(under 1 cent),... if not then "liquid" sidechain needs to do transactions for atleast 10cents (higher than bitcoins 0.0001).. liquid users will pay the 10cent premium for near instant transfers.. as people are stupidly happy to pay atleast 4.5cent for the hope of a 10minute wait.
thus bringing bitcoin back to being the cheapest option for transfer.
(we dont want liquid being the cheapest and fastest. as thats a game killer for bitcoin)

those wanting to be full archival nodes can buy a 2tb hard drive for $100 and be ok for 20 years at 2mb block. or 5 years if block sizes doubles and doubles again rapidly

if you can watch netflix in HD then bandwidth is not a problem for you

then let it be the client side can have variants of how to handle transactions, rather than the main protocol endlessly needing  tweaking to suit every idea imaginable
