Views Exposed filter UX: omit default and empty exposed filter values from URL

When I use views exposed filter with pager, each pager link contains all arguments, used in exposed filter, so even if I don't touch any exposed filter values - pager url contains many garbage empty and default arguments, for example:

http://example.com/catalog?manufacturer=All&price[min]=&price[max]=&power[min]=&power[max]=&width[min]=&width[max]=&height[min]=&height[max]=&depth[min]=&depth[max]=&sort_by=field_price_value&sort_order=DESC&page=2

instead of clean way:
http://example.com/catalog?page=2

Same problem if I use exposed filter and change only one field value, URL contains all values, including empty and default:
http://example.com/catalog?manufacturer=Hypnotoad&price[min]=&price[max]=&power[min]=&power[max]=&width[min]=&width[max]=&height[min]=&height[max]=&depth[min]=&depth[max]=&sort_by=field_price_value&sort_order=DESC

This give many problems with search engine indexing of Views filter results - URL contains many unnecessary values, and if we add new field to exposed filter or reorder fields - each old URL filter will be changed, so search engines will see many new urls and will reindex it, and exclude them as duplicated content.

Best solution for this problem is compare current exposed filter values with default, remove empty and default values and leave only actual used defined values.
