WHY are some combis fitted with an integral or fixed filling loop?

[rizla01]

I have a main Eco 30 that i am working on and the Filling loop needs replacing.
OE is £60. There are a few online around £30 (4 day wait) or I can use a flexi.

Just wondering which way to go here.
Also it is always advised that flexi's be removed - WHY since the fixed one obv isn't.

1. Some combi's are fitted with and integral filling loop:
a. For ease of installation - its all in the box.
b. To make money for the manufacturer when they need replacing.

2. Go for an external. More choice = better price.

3. The flexi should be removed to eliminate the risk of the cold water supply being contaminated from the primary circuit. Its a water regulation, more honoured in the breach.

... When the parts wear out , because someone gets to point they re-pressurize 3 times a week .
(because of un-diagnosed cause )
they need to spend even more on expensive parts -- especially if part of BOILER
