That kinda tracks with how he usually gets power upgrades throughout his runs. Usually it's in the heat of the moment during do or die situations where Miles is able to tap into an unexplored part of his abilities and then we get to see him start to experiment with it later on. To what extent depends on the writer of course.
His Ultimate Universe comic run under Bendis capped off with introducing his Super Venom Blast against Hydra and Ultimate Dr. Doom.
His first 616 book, again under Bendis, saw him explore that, and near the tail end of the run we got the energy webs from his fingers (not sure if those are ever coming back though), and the first implementation of Miles using his bio-electricity to super charge his punches, debuting the Venom Strike.
Under Saladin Ahmed's run we can now see Miles being able to use his Venom Blast from short to medium distances instead of it only being through physical contact, and we got a glimpse of him using his venom blast for propulsion to launch himself far distances.
I'm all for Ziglar putting his own stamp on Miles evolving power set, and the notion of him creating bio-electric hard energy constructs is freakin awesome. Wouldn't mind an upgrade to his camouflage also though. Like maybe have Miles capable of camouflaging others as well.
I find it kinda funny to think about how Miles' powers have grown and matured along with him in a similar vein to puberty; especially since he was bitten at 13 right before it kicked in.
