Useless modifier in consructor here (even the constructor is empty, just why the modifier there, it makes no sense)
Bad assumptions to calculate the number of block passed here. BLOCK_TIME is an immutable variable which is passed as a parameter to the constructor. However, with future updates to the Ethereum protocol (IDK, reth or other validation algorithm) which could reduce that number would mean that functions dependant on that to work incorrectly like readInstantaneousReserves or _readCumulativeReserves. 
Do not assume the block rate to remain constant in the future or implement some function that modifies the BLOCK_TIME every T seconds/minutes/whatever.
