ELI5: What's the point of 24 or 48 port Gigabit switches having SFP uplinks instead of SFP+?

If you look at Cisco WS-C2960L-48TS-LL, it has "48 10/100/1000 Ethernet ports; four 1-Gigabit Ethernet small form-factor pluggable (SFP) module uplink slots". Isn't 1Gb SFP severely limiting the switching capacity on these switches? Does it purely boil down to the cost and the targeted customers? Sure, you could setup LACP on the 4 SFP uplinks, but why not have a single SFP+ instead or maybe even 2 for redundancy instead to keep the cost under control?
