I think no sponsor has a very valid point - taking on such a large debt narrows the choices you will have when you complete your studies no matter which route you take.
When you need to repay £650pm your options are limited and may restrict the decisions you can make that will affect your future aviation career. For me, flying turo-props round the Scottish Islands sounds fun for a few years but not if you are servicing such large repayments at the same time.
No matter what people's emotions says, getting into the flying industry is, at some level, a business decision (because we will work for businesses, train at businesses and borrow money from businesses).
However, to me the business case of £50,000k+ loan simply doesn't stack up with the current job market and opportunities within the next 18 months - this goes for Mod or Integ.
