The latency is not a problem as long as you avoid packet losses. If you have losses then you pay dearly if there's latency. The latency itself doesn't present a problem, the TCP window size increases and takes care of that. The problem is packet losses, because (even with 'intelligent' retransmission) there's a lot of (the buffered) window to retransmit and then the performance dies. When the packet losses stay low, say, 0.001%, the latency is not an issue.
(At work I did months of testing on TCP performance for a 900ms rtt high-speed link)
But yes, upload speed is more important than ever. For my work-from-home setup I need to transfer lots of data both ways. And for my "cloud" backup etc. I need to push large amounts of data out of the house. And with fiber I get that, fortunately.
