It seems that if you really want a very/light compact travel zoom, an "all-in-one-solution" as small/as light as possible, there is no alternative out there.
@Richard Wong demonstrated that in his video very good. No matter which zoom alternative you choose, it is always a compromise and you have to choose depending on your preferences with the focal range. 28-200 alone or the 14-28 plus 20-60 or 20-60 plus 70-300. And if you consider Sigma zooms too, there is even more choice and combinations possible for L-Mount users.
I think the 28-200 was a smart move from Panasonic. This will bring more customers in, who do not want to switch lenses.
But hold that thought...
If I would be Panasonic, I would bring out a new camera body that fits to that lens and target group. A cheap and small Lumix body. No great video features. Keep it simple and cheap. Offer it as a kit with the 28-200 as the kit lens for a very aggressive price to gain market share.
