What are concrete uses of Bitcoin script?

I am looking at solutions to simplify the architecture of Bitcoin from a more theoretical perspective. I am thinking about removing Bitcoin script, however I am not sure what restrictions this introduces. I find many vague arguments, that having script makes us more flexible, however I am looking for concrete examples.

I have the following things:

Payment channels
Gambling / distributed random generator
Storing data in the blockchain / Proof of publication

What else is out there?

1Are you thinking of using the P2PKH as the only way of sending transactions? (Just to clarify what examples can be suggested) – sr-gi – 2017-02-24T15:30:37.587

I'm wondering whether your underlying question is: "What are the advantages of having a script language for transactions instead of a more simple transaction format?" Perhaps you would like to edit your question to specify your question more clearly and to tell us a bit more about what we would be comparing to. – Murch – 2017-02-27T10:21:04.277

multisig transactions
blockchain-embedded escrow
time-bound transactions
proof-of-burn
bets based on some oracle, either trusted or decentralized

I suppose there are many more and that some if not all of the above can be, more or less efficiently, realized with P2PKH, possibly with some extra protocols required.
