McLaren are in their third year of a long-term contract with Honda, but are the only team without a single point to their name this season following a terrible start to the new campaign.
After the failure in Canada, team boss Zak Brown described Honda's situation as "lost" as speculation intensifies that McLaren are prepared to ditch Honda and return to Mercedes power in 2018, after the disaster of the Honda project from 2015 onwards.
It will be a massive humiliation for McLaren, who have won 20 world titles stretching back to 1974, and on a street circuit where overtaking is virtually impossible.
"That would be great for the sport", Hamilton said.
"McLaren belong at the front with the top teams". They have had a disaster of a time over the past few years.
"It's a total waste and an absolute travesty that he's at the back of the grid, driving a auto that's uncompetitive", Webber explained to GPUpdate.net on Thursday when asked about the two-time world champion, who is being strongly linked with an end-of-season move after three years back at McLaren.
Alonso has yet to make the podium with his Honda-powered McLaren and there have been very few signs of improvement, the two-time world championship failing to score a point this year while recording three DNFs.
"That would be great for the sport", Hamilton added.
"I don't think we have high hopes, but we'll try our best from our side".
"It will be great if Fernando is up there racing with us at the front".
"If we start at the back it is going to be a hard weekend", he said.
Fernando Alonso does not sound enthused with the news that Honda has brought an upgrade for its hapless power unit to Baku.
