For me saying that internals are not important as long as transcript does what 
is expected from it, is like saying that Parser being a subclass of Scanner and 
Compiler being as subclass of Parser is ok as long as it compiles source code. 
We already had that and it was bad.

On the other hand it’s obvious that we don’t have enough resources to rewrite 
Pharo from scratch and we cannot leave issues as they are just because we 
cannot solve them perfectly now.

I would say that Igor is correct saying that we need a better architecture, and 
Stef and Eliot are correct saying that we need tools that fulfill users’ needs. 
And we have to say: “ok now we hack this around, but we have to do this the 
right way one day”. Is anyone familiar with same-css[1] concept?

P.S. maybe my 2 cents are useless, but all the fight around this discussion is 
really strange for me. In Ukraine we have a saying that it’s better to be 
healthy and poor than sick and rich. Now I use to say that it’s better to be 
healthy and rich than sick and poor. And all the fight here was if it’s better 
to be healthy or rich. Definitely it’s better to be both, we cannot do that 
instantly but we can set goals and milestones, and find the optimal strategy.
