First, let me say I'm totally on board with the increased rarity of magic items and such in 5e, including acquired spells and what have you.
However, when you are a Tome Pact warlock, this puts a huge amount of your subclass's primary feature in the hands of the DM. If your DM is forgetful or stingy, or if he/she just doesn't get that rituals are the thing that sets you apart from other warlocks, you might go your whole life with only two 1st-level rituals in your Book of Shadows.
Furthermore, if you are playing in a published campaign such as HotDQ, your DM might not see fit to augment the treasure drops as printed, and while I haven't read that campaign (because I'm playing in it), my suspicion is that there are few, if any, ritual books to be found as loot. (Feel free to spoil this point if I'm wrong.)
I don't feel like the player should have to negotiate or beg for more utility in his subclass's one and only stand-out feature. The cantrips are nice, mainly from a role-play perspective (Thaumaturgy for a hell-lock? Yes, please!), but if you never get more than the first two rituals, you're going to end up wishing you'd chosen Blade or Chain.
I'm just sayin', if I were to choose this path for my character, I'd try to get the DM to agree in advance to one new ritual every odd level at the very least. IMO, they should have made it part of the invocation.
