I also think that Rogues should get their Expertise and proficiency in Thieves Tools added. The last time I checked, picking locks instead used Sleight of Hand. I feel like that tying lockpicking proficiency to SoH instead of TT acts as a bit of a skill tax on the Rogue. Admittedly Rogues do get more skills than others, but I see no reason why they shouldn't get TT proficiency.
That said, I think I've also seen some descriptions which suggest that other types of tools will be added, like herbalism kits, so perhaps when tools are added, Rogues will gain proficiency in the Thieves Tools.
I think the best solution would be to give Rogues proficiency in Thieves Tools and keep Sleight of Hand also granting proficency with Thieves Tools. That is homebrew, but it allows for more classes to have access to proficiency in Thieves Tools without tying themselves to that background, while also not being a skill tax on the Rogue which goes against the PHB.

I also think that with the exception of Revivify scrolls, classes should only be able to use scrolls with spells from their class spell lists. I think this will be in eventually, but right now it apparently isn't high enough priority or is more complicated to implement than expected.
