I'll give you an analogy, show you what I mean:
Let's say Core devs are building a railroad, and drawing pay from Mayor Mccheese.
The railroad can go through the plains, which will take it right through Hamburglar's Town, or it can go over the mountains, which would take it right through The city of Mccheese.
better analogy
public railroad engineers for 7 years had a railroad with a single track that tunnelled through a mountain to get to the town
everyone had to get on a train that only allowed 2500adults and 2000children onboard per train every 10 minutes
but the town wanted to expand
trying to change it so that the trains departed every 2 or 5 minutes was impossible and would break the rail road completely. no one would do that ever..for good reason
so the HARD option is to excavate the tunnel to allow a reinforced track that could cope with larger trains to allow 5000adults and 4000 children per train every 10 minutes
or the Soft option. to make a second track that goes around the mountain.
but to do this the trains needed to change to ensure it didnt damage the track.
the private company called secondrail wanted the soft option because later they could use the soft track to divert to other towns like lightnington or sidechaina
however this soft track only works with the adults getting on the main track and the children have to get on the new soft track. and would only see an overall capacity increase if the adults made a decision to separate from their children.
the private company called secondrail funded some of the public railroad engineers for the design, labour and construction of the soft track, adding a non-compete clause.
a couple public railroad engineers didnt sign and done other things one resigned and one set up his own track company that had plans for the Hard option
the private company called secondrail made some passenger concessions such as "children can have a free ticket" so the adults see a cost reduction. hoping it would please the passengers to agree
the private company called secondrail made some threats that if the soft track was not accepted by the town they would demolish the tunnel. to scare the town into agreeing
...
This is a lot to absorb.
Wouldn't it be more correct that they said widening the tunnel will cause a collapse and destroy the security of the rail?
So a soft rail needs to be created to protect the first rail from such a failure.
